Given the following set of numbers: 3.3, -2.3, -16, 25. What are the square roots of the
whole number?
A. +/- 2.3
B. +/- 3.3
C. +/- 4
D. +/- 5 -CORRECTANSWER D. +/- 5
Composite Number -CORRECTANSWER A number with more factors that just one and
itself.
Equivalent Fractions -CORRECTANSWER Different fractions that represent the same
value.
X-Axis -CORRECTANSWER The horizontal line that passes through the origin on a
coordinate plane.
Qualitative Data -CORRECTANSWER Non-numeric information based on some quality
or characteristic.
,No Correlation -CORRECTANSWER There is no apparent overall trend between the
two variables. If the correlation coefficient is 0, this only rules out a linear trend. There
could be a non-linear or curvilinear trend.
Extrapolate -CORRECTANSWER Using information from a data set to make
predictions about data outside of the original set.
Event -CORRECTANSWER An outcome, or set of outcomes, whose chance of
occurrence can be represented with a probability.
Given the following set of numbers: 10, 2.5, -4, -4.5, 5. What is the sum when adding
together only the whole numbers?
A. 5.5
B. 11
C. 12.5
D. 15 -CORRECTANSWER D. 15
Operation -CORRECTANSWER In Mathematics, an operation is a procedure which
generates a new value from one or more operands, or Mathematical values.
Conditional Proportion -CORRECTANSWER A proportion where one part of the
proportion is a variable, or unknown quantity.
, Coefficients -CORRECTANSWER A number by which a number is multiplied. This
number is written in front of the variable(s).
Mean -CORRECTANSWER Average, calculated by adding a series of elements in a
data set together and dividing by the total number in the series.
Outlier -CORRECTANSWER An observation point that is statistically distant from the
other observations in the dataset.
Regression Line -CORRECTANSWER The line of best fit to show the relationship
between variables, the one that minimizes distance from each data point to the line.
Experiment -CORRECTANSWER A procedure that can be done repeatedly which has
a well defined set of outcomes.
Given the following expression: 4 + 7 × (6 - 3)2. What is the CORRECTANSWER using
proper order of operations?
A. 25
B. 46
C. 67
D. 99 -CORRECTANSWER C. 67
